| 摘 要： | 对四川江油1～3年生慈竹材主要物理力学性质进行了测定与分析,结果显示:竹材气千密度,全干密度,基本密度,顺纹抗压强度,顺纹抗剪强度随竹龄和竹秆高度的增加而增加:径、弦向全干缩率随竹龄和竹秆高度的增加而减小:径向全千缩率大于弦向:竹壁厚度随竹龄的增加而增厚,随竹秆高度的增加而减小.方差分析表明,竹材全干密度,基本密度,径、弦向全干缩率,顺纹抗压强度随竹龄变化在0.001水平显著;全千密度,竹壁厚度,顺纹抗剪强度随竹秆高度变化在0.001水平显著.

| Abstract: | The main physico-mechanical properties of 1-3 years old Neosinocalamus affinis timber produced in Jiangyou,Sichuan were determined.The results showed that the air-dried density,oven-dried density,basic density,compression strength parallel to grain,shear strength parallel to grain increased with the growth age and position height of the culm,while the oven-dried radial and tangential shrinkage ratio decreased.The oven-dried radial shrinkage ratio was higher than that of the tangential one.The bamboo wall th... |
